Western Digital Launches 14TB HGST Ultrastar Hs14

Ashley Allen / 7 years ago

Western Digital announced that it is releasing the world’s largest hard drive disk. Indeed, the monstrous HGST Ultrastar Hs14 – designed for industrial applications – boasts a whopping 14TB capacity. In fact, the Helium-filled drive offers 40% more capacity and twice the sequential write speed than its SMR predecessor. In addition, the drive features an MTBF of 2.5 million hours and comes with a 5-year warranty.

HDD scaling is becoming increasingly difficult, and 14TB is definitely the higher end of the potential scale. Note, though, that the HGST Ultrastar Hs14 is an industrial drive. At present, the biggest consumer HDD is Seagate’s 10TB Barracuda Pro. However, with a 16TB Seagate HDD en route, the HGST Ultrastar Hs14 won’t be a record-breaker for long.
